What is Enlightenment level?

Enlightenment is a characteristic you can increase by performing all kinds of actions in the basement: exploring rooms, fulfilling quests, charging collections, banishing monsters and also visiting your friends' basements. Increasing the Enlightenment level will let you open new rooms and receive new quests. Also sending some gifts requires a certain Enlightenment level. The higher your Enlightenment level is - the more opportunities you have in the game!
